One small sheriff’s department is waging war against human trafficking by posing as a prostitute online in order to catch offenders, revealing many unexpected perpetrators in the process including doctors and police officers.

Operation ‘No tricks, no treats’ began October 10 and ran to October 15. Individuals at the Polk County Sheriff’s Office in Florida posed either as ‘prostitutes’ or ‘clients’ soliciting adult industry workers on websites and social media sites.

Investigators reported that 209 of the arrests were for individuals accused of ‘soliciting undercover detectives’ and 51 arrests were made for individuals that displayed themselves as prostitutes online. There were 17 arrests made for other related offenses. NBC News has publicized a complete list of all individuals arrested.

Perhaps the most surprising arrest was that of Sgt. Luis Diaz, an individual who has worked at the Polk County Sheriff’s Office for 17 years.

“We are absolutely embarrassed. We hold our own accountable. He messed up and no longer works for the Sheriff’s Office” were the words of Polk County Sheriff Grady Judd.

Judd identified some of the other suspects arrested as a cancer surgeon, teacher, pediatrician, Air Force veteran, retired deputy sheriff, retired police officer, an active colonel in the U.S. Marine Corps and several pharmacists. They range in age from 16 to 74 years old.

According to Judd, this operation accumulated to the highest number of human trafficking arrests made in one operation in the history of the sheriff’s office.

“We are committed to fighting human trafficking, by arresting those who engage in prostitution and trying to identify human trafficking victims” Judd said.

The National Human Trafficking Hotline reports that there are 20.9 million victims of human trafficking globally, with approximately 700,000 persons annually trafficked within or across US international borders. The victims range in age and demographics and are as prevalent in rural areas and suburbs as they are in cities. These victims are largely targeted using tailored methods of recruitment and control to be compelled into forced labor or commercial sex. Some of the victims are kept locked away in brothels, while others are free to walk around and interact, and that includes soliciting on the Internet.
